Hi Doc,
The photo shows the Giant Sundial of Jantar Mantar in Jaipur, India. It is also known as the Samrat Yantra (The Supreme Instrument), stands 27m tall. According to wikipedia, its shadow moves visibly at 1 mm per second, or roughly a hand's breadth (6 cm) every minute!
I have many pictures of my travels so far on my blog site www.jamesto.multiply.com
Best regards
JAMES
